Edge stuck when moved with control points in FFD modifiers

[Anonymous]

Hey guys, I need help with this FFD modifiers. I stack this modifier after Edit Poly (while selecting polygons) & Bend modifiers  on a model and tried to move some control points, but unfortunately, there's like some edges that won't move and made it look like it was stuck for some reason. I've tried stacking Edit Poly before FFD, collapsing the modifiers, vertex welds and such, but the problem still there. I also have tried using FFD from 2x2 to 4x4, but still with the same results. I think it's just some software bugs. You guys know how to fix this?

I've attached a pic to show the problem. As you can see, I tried to move the control points of the polygon-selected area, but some edges (like the one in yellow circle), won't move at all.

Seems to work ok here. Could you post the scene (zipped) containing just that one object so we can take a look?

Nah, no need to. It seems that I have found the solution. I had to tick the "All Verticles" selection in Deform option down in FFD's parameters. I don't even know what that options mean, but it works. I never change the parameters in FFD modifiers before so I don't know why this happen. Thanks anyway.

I didn't change any of the defaults and it seemed to work ok here anyway. Glad you got it sorted 🙂
